GRAIN Application led November To all Lo/om t'mag/ concern.' p v Be it known that I, Mair li/IAno'rz, a citizeno the United States, residing at Ashton, inthacounty oFrernont and State ci IdaV ho, have invented certain new and useful Improvements in Grain Urills; and I do declare the following to be `a full, clear, and enact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same; Y Y

lThis invention relates to an improved operatinforV means for rendering the grain` feeding,N mechanism 'of a grain drill inop-V erative when soY desired, the operating means being so constructed that it YVis not necessary to lift the disks out of the ground. By meansv oi this 'operating mechanism, the eedingniay bestopoed whenever desired and feeding' of the grain can be started lt will thus Abe seen :that when making," a turn at the end of a lield, it is not. necessaryto lift the disks outY ol the ground to prevent eedinggoi grain'at the turn and further the feedingl ofthe seed can be set in operation iinn'iediately afl'ter the` turn is made instead of the ieedingi ci the seed being controlledby the `position of the disks with respect tol the ground and the feeding startedA either too soon or too late. p y Aanother object oi the invention is to so construct this mechanism that the feeding` oli the seed may be controlled by a-treadle lwhich may beioperated by thefoot ont the personoperatinf; the grain drill'.therebyl inalng; it unnecessary to use the hand for, controlling the feeding.` i n f. l

This invention is illustrated in the accompanying drawings, wherein:

Figure l is view showing onerside portionv oi a. grad-in drill in rear elevation with vFigure drill partially in side elevation in vertical section.

Figure 3 is a vertical. sectional view .taken along the line A3 3 or" Fig. l.

2V is a view showing the grain and partially view of the The grain drill is provided with the usual grain boi; l, having a conventionalV structure ofgrain feeding mechanism which includes `a rotatable shaft 2 at each end 'o DRILLQH 1,1921. semaine. 512,106. z`

which is provided y geary 2KL engaged by anidler gear 'Ll which when in an operative* position willifmesh/witlra gear carried by-thelaxler whichniay be terniedva drive shaft andicarries the supporting rwheels 7.l When the gearszl are inthe operative position and the `rain drill'is beingmoved forwardly, `the-axle ,6 will. rotatefwith the Vwheels and rotary. rn'ovenien'tA imparted to the kshaft '2.so that. grain inay be Jfed rout 1 through the grain spente, one'ot7 which is shown in Fig. Zand indicated by the nu-L meral y8 and any .number of which may be provided;L Adj|aeent eachend ot the grain box, there has been provided a bracket 9 which is pivotally mounted uponthe shaft 2 andserves as aj bearing bracket for the` idlergear 4f. A spring strip ldis secured to-thegrain box as shown at 1l' and :has engagement` with therbrackets yso 4that the brackets will be normally held in the posi-v tion shown in Fig.-2-butfmay be swung` up?v wardlygagaiust theaction'oil they springto `move the gear 4l outo engagement-with thegea-r :5 and thus prevent rotation of the drive shaft' V:3. YAn eye l2 is carried bythe bracket iand engaged'by a `'chain 13 which extends upwardly to engage the pulley wheel- 14: .earriedby the inwardly extending free* end portion of the bracketk 15' which is se-g cured to the ends of` thegerain box."r After the chain has 'engaged the pulley wheel 1.4j

the chain is carried toward the center olY the `grain boX and from an inspection ot Figs.Y l and 4it ywill be seen that the twoL chains whichextendfrom opposite ends of is provided at its lower end with bearing ears 119between which the foot treadle r20 is pivotally. mounted by means ot -a pivot pin 21'.'` ltheir* lower ends, thefchainglx erator of thegrain :drill places his foot, upon the treadle and pushes downwardly, l fthejchainsl'will be drawn upon and each oil:k ythese chains will .draw ,the bearing bracket 4with which is connected upwardthe Ygrain Ybox are brought intoengagenient with pulley wheels 16 rotatably mountedA in the heads 17 LVot thebracket 18. This. f bracket 18 lis secured in arvertical position -upon the rear` face of the grain boxfland ly'and causev the gear 4 carried by this bear- Ving bracket to be moved out of.' engagement with the gear driven across the eld with the furrow disks embedded in the ground the desired amount.

- W'henthe end of the field is reached and itv l 10 is necessaryto make a turn, the operator will place his yfoot upon the'treadle 201and press the treadle downwardly thus causing the bracketV 9 at each end to be swungup-- wardly to render the feeding mechanism of the grain box inoperative. It is therefore not'necessary to lift the disks outV of the ground. The turn can therefore be made without the furrow opening disk being liited from the ground and when the drill is again in position to travel Vacross the field, the disks will be embedded in the ground the desired amount, and the seedmay be properlyy deposited. Itv has been found that where it is necessary to lift the furrow opening'disks before lmaking' a turn and then again lowering them after the turn is made, the disksdo not at rst extend into Athe ground the proper amount and therefore at the end oftthe field,the grain is not-properly placed in the ground. It has also been found that where it is necessary to descend l from the drivers Seat in order to render the feeding mechanism inoperative, the vdriver does not always take the trouble to do this and` therefore 'seed is wasted at' the turn. Vifhen the foot is removed Ytrom the treadle after the turn is made, the weight of the gears 4 and brackets 9 will tend to return the brackets to the normal position with the gears 4 engaging the gears 5 andk this return will be assisted by the springs lOrwhich slid'- Y K ll is-inuse, the grain is` placed 1n the grain box and the drill is ablyyengage the brackets and serve to yieldably hold the brackets against upward swinging movement. There has thus been proif'ided means for controlling the feeding oit' grain from a grain drill which is so constructed that Vthe feeding mechanism may be. rendered inoperative wheneverdesired and again rendered operative without it being necessary to lift the furrow opening disks from Ythe ground or for the vdriver to leave the drivers seat ot' the grain drill;
